I've had the headphones for little over two months, when I first purchased them the right earcup (the broken side) sounded like it had something loose inside it (I actually made a forum post about this which is still available to view). It eventually stopped making the noise and I disregarded it. Earlier today I put them on and I heard a little snap, and I thought it was just the headphones adjusting, but it was actually the pivot point on the right earcup which had gave way.

I will provide some pictures if you would like to view them, excuse the quality. It is just to give you a general idea.

As you can see, the fracture is slightly above the earcup, it has just literally came to pieces, the earcup is now dangling from the headphones.
